I used osmocom-bb and grgsm with usrp b210 to connect openBTS, but failed. The command is "./mobile -c /home/oi/wf/osmocom-bb/doc/examples/mobile/default.cfg","./trxcon -p 5075 " ,"grgsm_trx -p 5075" .
When i used “./cell_log -A 1 ”, it could find plmn 1-1 with arfcn 1 which is same with openBTS.

But when test with sim testcard 1, it failed to find the 1-1 cell. Could anyone give any suggestion about this? Thanks a lot!

Hi there,
You have to give these things some time.
There are some good notes of expected behavior and bytes here: https://osmocom.org/projects/baseband/wiki/CompalRamloader
